Economic geologists have attached increasing importance to the magnesian carbonate formations in that these formations produce many large or superlarge deposits such as talc, magnesia, massive brucite, borate, and serpentine deposits. In this paper, the mineral deposits and four minerogenetic series of nonmetallic mineral deposits in magnesium-rich carbonate formations within eastern Liaoning peninsula, eastern Shandong peninsula, eastern Qinling Mountains and northern Guangxi and their minerogenetic conditions were discussed. The authors believe that nonmetallic mineral deposit series was formed by comprehensive activities of tectonic-fluilds-metallogenic system from ore-source layers under certain tectonic conditions.
